The Molex 430450413 is a 4-circuit, dual-row header from the Micro-Fit 3.0 43045 series. It's a board-to-cable/wire connector — the male pins mate with a Micro-Fit 3.0 receptacle housing to make a wire-to-board interconnect. Typical applications include automotive harnesses, industrial control cabinets, medical equipment, and telecom gear — any environment where a vibration-resistant, lockable power or signal connection is needed.
The 8 A per contact is a solid power rating for a 3.00 mm pitch header — sized for DC distribution or moderate-power loads, not just signal duty.
Through-hole termination with kinked pins for retention before soldering. The square pin contact shape mates with standard Micro-Fit 3.0 crimp terminals. The UL94 V-0 glass-filled LCP housing handles wave-solder temperatures without distortion. The 0.125-inch post length is a standard through-hole dimension for typical 1.6 mm PCBs.
